Affordable replacement
Worked perfectly with my Black & Decker string trimmer

Charge when you are not in a hurry because it takes almost 3 hours to fully charge.
Lots of power.

Tight fit on the charger
Seem to be working well. The only issue I encountered was that the new replacement batteries didn't fit very well with the original B&D charger. It appeared to be the new batteries were just a bit too wide, but with a little bit of pressure, I got them on. Not as difficult to attach them to the weed eater. Batteries had a nice, strong charge, and worked well as replacemnets.

I do not trust any of the batteries sold on Amazon by mutiple sellers and these are the worst.
Like most Amazon suppliers, as soon as there are enough bad reviews, they just change the name not the product. There are a heap of B&D type batteries being sold by several dozen companies with wildly varying specs. I think they are a bunch of "suppliers" all selling batteries being manufactured by the same company. Each slaps a label on it with their name and spec. I bought these claiming to be 4 amp hour rating in the same case size as my B&D supplied 1.5 &2.0AH batteries. These from Amazon weigh 300 grams and B&Ds weigh 320 and 350grams. Seems impossible to me. I asked for test data from the supplier and they said just try them. I am returning them. For a saws-all to work for any time needs a long lasting battery. The third time I charged one of then it failed. I used it on a saws-all and I think the batteries are so cheap construction just burn up with use. I am down to one and I have only used them a couple of times.
